This invention relates to pouring spouts for vessels containing liquids whereby any drips of liquid forming at a pouring mouth or lip are caught ina gutter arranged round this pouring mouth or lip and are returned to the interior of the vessel.

The object of the invention is to provide such a pouring spout with means whereby the drips of liquid caught in the gutter are continuously returned to the interior of the vessel by the action of capillarity.

A further object of the invention is to provide the the capillary entry of the drips of liquid to the interior of the vessel is supplemented by -a return by gravity.

Some embodiments of a pouring spout according to the invention are illustrated by way of example in the accompanying drawings, in which:

Figs. 1, 2, 3, 4 and 5 show the constituent parts of one form of the pouring spout.

Fig. 6 shows the pouring spout assembled.

Fig. 8 is a cross section taken along the line AA in Fig. 7.

Fig. 9 shows a modified form of th spout. 2

Figs. 1 11 and 12 show in elevation, plan and vert cal section, respectively, a further modificatlon of the pouring spout with cover for the same.

- Figs. 13 and 14 show a modification of this cover.

Figs. 15 and 16 show still further modifications of the pouring spout.

Figs. 17-21 illustrate other forms of the pour-mg spout.

The device shown in Figs. 1 to 5 comprises an annular stopper'A made of cork or any other suitable material, a tubular body B, preferably metallic, which has'at its upper part an abrupt bend and a spout a and at its lower: part a circular internal rim or flange b, a tubular body G forming the pouring member, also preferably metallic, slightly curved forward at the upper part c which forms a spout, slotted. at (1 along a generating line diametrally opposite the spout and slightly pouring pouring spout with means whereby pressed in at e and e: to form two wing shaped parts.

Fig. 6 shows the manner in which these various parts are assembled together.

Then the body B has been engaged in the stopper A, the tubular pouring member G is pushed therein and, on account of the fact that it is slotted, yields with suflicient elasticity until its lower end abuts against the flange B. Further, in order to facilitate assembly, the two parts are held in engagement by a punch mark formed in each part during construction at f.

This pouring s out arrangement will be mounted upon a ottle in the same way as an ordinary stopper. It is seen that the spouts or lips a and a have their axes in the same vertical plane. When it is not desired to make use of the contents of the vessel, the

whole pouring arrangement may be covered 7 with a cap such as'D shown in Fig. 5, constructed of wood or metal, or'of any other suitable material. This cap D bears upon the conical part G of the stopper, or upon any other suitable bearing surface formed for receiving it, either upon the body B or upon the container itself.

The operation of this pouring spout, which is explained by the observation of certain phenomena peculiar to hydrodynamics and the surfacetension of liquids, is as follows:

When the containing vessel is canted over, the liquid is made to flow out through the spout C. It must be noted that, on account of the rim or flange b the liquid tends to jump over the joint which separatesthe parts B and C so that the liquid in movement will not penetrate into the annular space separating the parts.

The. flowing liquid then meets the two wings e, and 6 which deflect it on to the opposite or spouted side of the pourer C. ,When it has reached the end of the pourer C the stream of liquid tends, by virtue of its sur face tension and on account of the lip or spout a being itself slightly curved, to adopt a circular cross section. It then escapes in cylindrical jet,

the form of a well guided and substantially to avoid soilin When the Containing vessel is righted again, a dro or trickle of liquid is? formed beneath the beak or spout '0. The weight of this trickle causes it to descend along the outside of the beak C and its surface tension keeps it against the tubular member until it reaches the annular space Y separating the parts B and C. The surface tension then acts in a. two fold manner and this drop spreads rapidly in the space between the surfaces B and C. In most cases the action of capillarity is sufficient to make this drop reenter the container by the path of the capillary ring formed between the two surfaces,

the outlet from which path is formed by the channel 03 and the rim 1).

When the drops are numerous they collect under the eflect of surface tension and gravity in the space comprised between the ody B and the Wings 0 and c They then ass into the interior of the tubular member either by overflowing the wings or by following the channel formed by the slot d. The capillary space then removes the remaining drops.

It will be seen that this embodiment of the invention, in addition to providing for a liquid to be returned to the container by capillary attraction, also provides for surplus liquid to drain back into the containing vessel by the simple action of gravity, the combination of these means being in some cases desirable, but it is to be clearly understood that the liquid may be returned by capillary attraction only. i

Among the advantages presented by this pouring spout arrangement must tioned that of reat cleanliness. Not only are particles of liquid which trickle down the sides continually re-absorbed with the pour ing spout described but drops are also carried back very rapidly into the container itself without remaining upon the device.

Moreover, the pouring spout comprises no mechanical or delicate member in which The embodiment hereinbefore described is very simple, is dismounted by a simple ull and can be cleaned and even disinfecte in a few moments.

/ The device may be employed for various purposes,'for wines, oils, syrups, perfumes, solutions of sodium hypochlorite for cleaning and bleaching, vinegar, acids, table water, inks, etc., in all cases when it is desired table linen, burns such as those produced y caustic liquids, soiling the outside surfaces of flagons, or unpleasant contacts with fatty or syrupy liquids which have overflowed their 'cont'amers.

Various other forms of this pouring spout may be adopted. I

Thus, for example, it may be constructed be men-,'

at the same time as the container, certain of 7 its parts being formed upon the latter.

In a general manner, the embodiment of the invention hereinbefore described is only given by way of example, and modifications may be made in the shape, dimensions and materials employed for the members, without on that account, going outside the scope of the invention.-

The outer tubular member may be modified, as shown at B in Fig. 9 and comprise a small collar I which is adaptedto abut against the stopper A.

Figs. 10, 11 and 12 illustrate a modification in which the outer tubular member B of the deviceis itself made to form a stopper and is provided with a flange p which may be of" varying size. A rubber ring n engages in a groove m formed in the member B above this flange and a cover D is adapted to grip this ring and, in the form shown in these figures, abut against the flange when placed in position, an operation which only requires the exertion of a simple pressure. Dust or air is thus prevented from entering the container. The flange also permits the whole device to be placed in position on the container or withdrawn in a very clean manner, by taking this flan e between the fingers.

In the case of dangerous liquids which it is desired to enclose with safety, the cover may be provided with a plug made of cork,-

Naturally, the usual closing devices may be employed, either separately or at the same time as the cap and the rubberring n.

Instead of making the internal member descend as far as the inner end of the stopper, as shown for exam le in Fig. 12, this member may be stoppe off at a certain distance from the inner end, as shown in Fig. 15, in which the outer member B of the pourer is formed with a shoulder .9 against which abuts the inner member 05: In this embodiment the stopper is formed in two parts A and A and the groove m and the flange p are formed on the part A As stated above, the liquid may be returned to the container b capillarity alone.

Fig. 16 shows, y way of example, a pouring spout in which the drops re-enter simply through the capillary space formed between an outer tubular member B and an inner pouring member C In this example, the

cover D, itself carries the closing ring n by means of which it is bet B4- Fig. 17 illustrates a telescopic pouring engaged over the memthe latter is pulled out.

spout mounted on a can R. In this embodiment of the invention the inner pouring member 0 may be at a considerable distance from theouter member B for pouring purposes, and on the contrary,located within the said outer member after use. In this case,

the drops which are formed at the pouring member 0 flow down along the tube-C and are collected in the gutter or groove G formed between C; and B lVhen the tube C is pushed into the can the pouring member 0 takes up the position 0' shown in dotted lines, so that the drops which were at the bottom of the gutter G reenter through the point C, in the pouring member and then'enter the can R.

Figs. 1821 show modified forms of a telescopic pouring spout, and illustrate various ways in which the pouring member may be drawn out.

In Fig. 18 a cover D adapted to screw upon the outer member 13,, is provided with a hook K which can be engaged under a pin T, secured to the inner slidable pouring member 0 in order to pull the latter out In Figs. 19 and 20 a suitable slot N is formed in the pouring member, and a hook K on the cover is adapted to engage in this slot for pulling out the pouring member. Qther suitable means for enabling the pourngdmember to be drawn out may be imagme I Fig. 21 illustrates a pouring spout similar to that shown in'Fig. 17, but with the difference that a receivmgmember B follows the movement of the pouring member C when is screwthreaded to receivea cover with which it will form a fluid tight casing in which the pouring member is enclosed after use.
